Scientists find evidence that real perceptual experience and mental replay share similar brain activation patterns.

Toronto, Canada - directly experiencing the real moment can trigger similar brain activation patterns.

The study, led by Baycrest's Rotman Research Institute (RRI), in collaboration with the University of Texas at Dallas, is one of the most ambitious and complex yet for elucidating the brain's ability to evoke a memory by reactivating the parts of the brain that were engaged during the original perceptual experience. Researchers found that vivid memory and real perceptual experience share "striking" similarities at the neural level, although they are not "pixel-perfect" brain pattern replications.

The study appears online this month in the Journal of Cognitive Neuroscience, ahead of print publication.

"When we mentally replay an episode we've experienced, it can feel like we are transported back in time and re-living that moment again," said Dr. Brad Buchsbaum, lead investigator and scientist with Baycrest's RRI. "Our study has confirmed that complex, multi-featured memory involves a partial reinstatement of the whole pattern of brain activity that is evoked during initial perception of the experience. This helps to explain why vivid memory can feel so real."

But vivid memory rarely fools us into believing we are in the real, external world - and that in itself offers a very powerful clue that the two cognitive operations don't work exactly the same way in the brain, he explained.

Early Neglect Alters Kids' Brains

Malawi Orphanage

Until the 1990s, the orphanages of Romania were notorious for their harsh, overcrowded conditions. Those perceptions have been borne out in new research that finds growing up in such an environment can change the brain for good.

Institutionalization in early childhood can alter a child's brain and behavior in the long run, the research finds. Fortunately, early intervention can stave off the effects.

The study, conducted with children growing up in Romanian orphanages, reveals changes in the brain composition of kids who spent their first years in institutions versus those who were randomly assigned to foster care. The findings point to a "sensitive period" in the brain for social development, said study researcher Nathan Fox, a child development researcher at the University of Maryland.

"Infants and young children expect an environment in which they are going to interact and receive nurturance, not only food, but psychological nurturance, from adult caregivers," Fox told LiveScience.

The finding adds to evidence that early childhood experiences can have lasting impacts on the brain, with one recent study showing that child abuse may shrink regions in the brain's hippocampus.

Children in foster care develop resilience through compassion

A new study shows that a therapeutic intervention called Cognitively-Based Compassion Training (CBCT) appears to improve the mental and physical health of adolescents in foster care. CBCT is a tool that provides strategies for people to develop more compassionate attitudes toward themselves and others.

It is well documented that children in foster care have a high prevalence of trauma in their lives. For many, circumstances that bring them into the foster care system are formidable -- sexual abuse, parental neglect, family violence, homelessness, and exposure to drugs. In addition, they are separated from biological family and some are regularly moved around from one place to another.

Emory researchers conducted the study in collaboration with the Georgia Department of Human Services (DHS) and the Division of Family and Child Services (DFCS). The study was recently published online in the journals Psychoneuroendocrinology and Child and Family Studies.

"Children with early life adversity tend to have elevated levels of inflammation across their lifespan," explains Thaddeus Pace, PhD, lead author on the paper in Psychoneuroendocrinology, and assistant professor in the Department of Psychiatry and Behavioral Sciences at Emory.

"Inflammation is known to play a fundamental role in the development of a number of chronic illnesses, including cardiovascular disease, type 2 diabetes, dementia, cancer and depression."

The study finds that adolescents who practiced CBCT showed reductions in the inflammatory marker C-reactive protein (CRP), reduced anxiety and increased feelings of hopefulness. The more the study participants practiced, the greater the improvement observed in these measures.

Using Twitter To Identify Psychopaths

Bateman

People's nasty traits have a way of revealing themselves on social networks: in writing. Or rather in how they write. That means an analysis of how someone tweets could reveal whether he or she is narcissistic, Machiavellian, or psychopathic, according to researchers who plan to present their findings at DefCon next week.

What are some of the Twitter stylings of these undesirables? Curse words. Angry responses to other people, including swearing and use of the word "hate." Using the word "we." Using periods. Using filler words such as "blah" and "I mean" and "um."

(I suspect that an analysis of the Twitter streams of many a blogger would suggest they are potentially a narcissist, a psychopath or an avid reader of "The Prince." Which may well be an accurate assessment.)

"The FBI could use this to flag potential wrongdoers, but I think it's much more compelling for psychologists to use to understand large communities of people," says Chris Sumner of the Online Privacy Foundation, which collaborated with Florida Atlantic University and big-data competition site Kaggle to conduct the study. He imagines the algorithmic models his team developed could be used to compare character traits between different countries based on Twitter.

Near Death Experience - Former Skeptic Shares Glimpse of Heaven


A self-described cynic, Dr. Mary Neal had her view on spirituality radically altered during a near-death experience on a kayaking trip on a remote Chilean river in 1999.

With her capsized kayak pinning her under the surging water, Neal was believed to have not been breathing for anything between 15 and 25 minutes, according to the kayaking guides with her on the trip. During the time of what she terms her "drowning," she claims to have had a heavenly experience in which she returned to God and was in the presence of Jesus and angels.

It was a life-changing event for a person who was not fervently religious. The incident also prompted Neal to write her best-selling book, To Heaven and Back: A Doctor's Extraordinary Account of Her Death, Heaven, Angels and Life Again, which spent several weeks atop The New York Times' "Paperback Advice & Misc." best-seller list.

"I would never claim to have been particularly religious beforehand,'' Neal told Matt Lauer during an in-studio appearance on TODAY Thursday. "I certainly believed in God. I think I was very typical. I sort of hoped there was something more and there was a reason that we were here, but I was very busy. I didn't put spirituality in the forefront of my life.''

A spinal surgeon from Wyoming, Neal suffered two broken legs and lung problems as a result of the incident, spending a month in the hospital and missing six months of work while in a wheelchair. As a doctor, she is used to having a biological explanation for near-death phenomena like bright lights and warm feelings, but believes this was a different situation.

Task-Oriented Cognitive Biases Drive The Highly Motivated

It feels daunting when we draw the bow across a violin for the first time or start learning to samba, or pick up our first stuttering words in a foreign language. The ultimate goal of being able to dance, speak French or play the violin seems a long way off.

There is a strong temptation to give up and try other goals, perhaps less challenging ones. So how do we motivate ourselves to keep going?

Consciously we can use these 11 goals hacks described in a previous article. But our unconscious also chips in to change our perceptions and help us on our way, as revealed by an ingenious new study (Huang et al., 2012).

Positive Psychology Theory of Happiness "Flourish" Lacks Humanity

While trying to survive (as opposed to thrive) is the new normal, increasing numbers of people still debate the nature of happiness. I am not a gloomy person, but I don't spend a single minute working at being happy. Nonetheless, I understand the impulse, which has become a national obsession, the central topic in a plethora of best-selling books, the darling of big business and the media and a boon for motivational speakers and self-help entrepreneurs. In a world as complicated and disheartening as ours, who wouldn't want to have a method for feeling better?

The problem is that this happiness quest is, at its core, an inherently solipsistic and hedonistic enterprise - me feeling better. I like feeling good as much as the next person, but the pursuit of happiness alone is a narrow and ultimately unrewarding vision of a full human life - as even Martin Seligman, the founder of the positive psychology movement that helped spawn the happiness industry - now admits. "Happiness" is "so overused," he writes in his book, Flourish: A Visionary New Understanding of Happiness and Well-Being, "that it has become almost meaningless. It is an unworkable term for science, or any other practical goal such as education, therapy, public policy, or just changing yourself."

Consciousness: The Untamed Frontier Of Cognitive Science

In a mood-lit University of Quebec auditorium with red velvet seating, hundreds of researchers gather for the 2012 Summer Institute in Cognitive Science. Some of the field's biggest names are in attendance -- there's emininent philosopher John Searle, to whom we owe the "Chinese room" thought experiment; rabble-rouser Dan Dennett, who argues with panache that self-awareness is an illusion; Stevan Harnad, the theorist who reshaped robotics in his youth by defining the (still unsolved) "symbol grounding" problem"; and Simon Baron-Cohen, psychopathologist and top expert on autism.

While the world celebrates the discovery of the Higgs boson, these scientists are hard at work on one of the most profound mysteries left: Why, and how, did humans became conscious?

Many of the experts in attendance, like David Rosenthal, believe that consciousness is the exhaust of the brain, which arises from the neurological processes that actually control our actions. While being conscious may enrich our lives, it has as much influence on our behaviour as a paintjob does on the inner workings of a car. This is often called the "Steamwhistle Hypothesis", for early proponent Thomas Huxley, who compared consciousness to the steamwhistle on a locomotive -- it clues us in to what the train is doing, but it has no power to change it.

Actions don't always speak louder than words - At least, not when it comes to forgiveness

Baylor University researchers examine restitution vs. apology.


People are more likely to show forgiving behavior if they receive restitution, but they are more prone to report they have forgiven if they get an apology, according to Baylor University research published in the Journal of Positive Psychology.

The study underscores the importance of both restitution and apology and of using multiple measures for forgiveness, including behavior, said Jo-Ann Tsang, Ph.D., an associate professor of psychology and neuroscience in Baylor's College of Arts & Sciences.

"One of the main reasons for using behavioral measures in addition to self-reporting by individuals is that they can make themselves look better by only self-reporting, although they don't necessarily intend to lie," she said. "And it may be that 'I forgive you' is a more conscious feeling if they receive an apology."

In the study, 136 undergraduate psychology students were stationed in individual cubicles and told that raffle tickets for a $50 gift card would be given out in three rounds, with 10 tickets per round to be divided between a participant and a unknown "partner." They also were told they might receive a note from the partner.

In the first round, participants were given only two of the 10 tickets split between them and their partners; in the second, they got nine. Some were told the distributions were made by the partner; others were told it was by chance.
